Review on Certified Performance Replacement Materials: Enhancing Compatibility for Optimal Results by Christopher Gonzalez

Kangen have two different filters, so look at the base of your old filter to make sure you've picked the right one! At the same time, this filter lasted 6 months with regular use. (Note: I'm single so for a couple I'd say 3 months is what you should be getting). In fact, after 6 months everything was working. Didn't slow down or clog. However. I noticed the water tasted like tap water and my machine said it needed a cleaning cycle (where you run water through the water until it stops saying "clean"), so I knew it was time to do it to replace. Make sure you clean your car every month or two as instructed. Here's a video: https://www.youtube.com/watch?v=edsrfXczxJU Also, you don't need to use Kangen cleaning bags. Simply purchase Food Grade Citric Acid here at Revain and use 2 heaping tablespoons in a cleaning cartridge. Hope that helps!
